FIG. 4 is a schematic block diagram of the touch device 10. The touch device 10 further comprises a main control unit 21, an input unit 22, a display control unit 23, a data storage 24, and a detection device 25. The main control unit 21 communicates with the input unit 22, the display control unit 23, the data storage 24, and the detection device 25 via data buses (not labeled).

The main control unit 21 controls the touch device 10 to display graphics, play video, communicate with other devices, and outputs control signals to the input unit 22, the display control unit 23, the data storage 24, and the detection device 25. The input unit 22, the display control unit 23, the data storage 24, and the detection device 25 operate based on the control signals. In one embodiment, the main control unit 21 is a central processing unit (CPU).

The input unit 22 determines locations of the touch display screen 12 that are touched and outputs corresponding sensing signals to the main control unit 21.

The display control unit 23 outputs image data to the touch display screen 12 based on the control signals. The touch display screen 12 displays images based on the image data.

The main control unit 21 generates information (hereinafter “holding information”) based on how the touch device 10 is held by the user. In one embodiment, the holding information comprises first information, which indicates whether the touch device 10 is held in the landscape orientation or the portrait orientation, and second information, which indicates whether the touch device 10 is held by a right hand, a left hand, or both the right and left hands. In the embodiment, the detection device 25 comprises a first contact detection unit 251, a second contact detection unit 252, a third contact detection unit 253, a fourth contact detection unit 254, a fifth contact detection unit 255, and an orientation detection unit 256. The first through fifth contact detection units 251-255 and the orientation detection unit 256 detect whether the touch device 10 is held by the left hand, the right hand, or both hands in the landscape orientation and the portrait orientation, and output detecting signals to the main control unit 21.

The data storage 24 stores first corresponding relations between the detecting signals outputted from the detection device 25 and the holding information. The data storage 24 further stores second corresponding relations between the holding information and display locations of the at least one shortcut mark A. The data storage 24 can be an EPROM, EEPROM, or Flash ROM.

FIGS. 5A-5F illustrate operation interfaces of the touch device 10. The second corresponding relations between the holding information and the display locations of the at least one shortcut mark A are as follows.

Referring to FIG. 5A, when the holding information indicates that the touch device 10 is held in the portrait orientation by the left hand, the display control unit 23 controls the touch display screen 12 to display a shortcut mark A at a first area adjacent to the first side surface 111.

Referring to FIG. 5B, when the holding information represents that the touch device 10 is held in the portrait orientation by the right hand, the display control unit 23 controls the touch display screen 12 to display a shortcut mark A at a second area adjacent to the third side surface 113.

Referring to FIG. 5C, when the holding information represents that the touch device 10 is held in the portrait orientation by both the left and right hands, the display control unit 23 controls the touch display screen 12 to display two shortcut marks A. A first shortcut mark A is displayed at a third area adjacent to the first side surface 111 and the second side surface 112. A second shortcut mark A is displayed at a fourth area adjacent to the third side surface 113 and the second side surface 112.

Referring to FIG. 5D, when the holding information indicates that the touch device 10 is held in the landscape orientation by the left hand, the display control unit 23 controls the touch display screen 12 to display a shortcut mark A at a fifth area adjacent to the fourth side surface 114.

Referring to FIG. 5E, when the holding information represents that the touch device 10 is held in the landscape orientation by the right hand, the display control unit 23 controls the touch display screen 12 to display a shortcut mark A at a sixth area adjacent to the second side surface 112.

Referring to FIG. 5F, when the holding information represents that the touch device 10 is held in the landscape orientation by both the left and right hands, the display control unit 23 controls the touch display screen 12 to display two shortcut marks A. A first shortcut mark A is displayed at the third area adjacent to the first side surface 111 and the second side surface 112. A second shortcut mark A is displayed at a seventh area adjacent to the fourth side surface 114 and the first side surface 111.

FIGS. 6-7 are schematic views illustrating locations of the first, second, third, fourth, fifth contact detection units 251, 252, 253, 254, 255 and the orientation detection unit 256 of FIG. 4. The first, second, third, and fourth contact detection units 251, 252, 253, 254 are located on the first, second, third, and fourth side surfaces 111, 112, 113, 114, respectively. The fifth contact detection unit 255 is located on the rear surface 116. Each of the first through fifth contact detection units 251-255 can detect multiple points of contact and output a number of first through fifth detecting signals corresponding to the multiple points of contact, respectively.

The orientation detection unit 256 is located between the enclosure 11 and the touch display screen 12, detects whether the touch device 10 is held in the portrait orientation or the landscape orientation, and selectively outputs a sixth detecting signal or a seventh detecting signal to the main control unit 21 based on the detection. When the orientation detection unit 256 detects that the touch device 10 is held in the portrait orientation, the orientation detection unit 256 outputs the sixth detecting signal to the main control unit 21. When the orientation detection unit 256 detects that the touch device 10 is held in the landscape orientation, the orientation detection unit 256 outputs the seventh detecting signal to the main control unit 21.

The first, second, third, fourth, and fifth contact detection units 251, 252, 253, 254, 255 can be resistive touch devices, capacitive touch devices, or other appropriate touch devices. The orientation detection unit 256 can be an accelerometer, a gravitation sensor, or other appropriate device for detecting the landscape and portrait orientations of the touch device 10.

Referring again to FIG. 5A, the main control unit 21 determines from the sixth detecting signal that the touch device 10 is held in the portrait orientation. The main control unit 21 further determines that a left hand of the user contacts more points of contact of the first side surface 111 than the third side surface 113. Thus, the display control unit 23 controls the touch display screen 12 to display the shortcut mark A at the first area adjacent to the first side surface 111. In one embodiment, if the main control unit 21 determines that opposite sides of the touch device 10 are contacted at a substantially equal number of points of contact, the display control unit 23 controls the touch display screen 12 to display the two shortcut marks A adjacent to the two opposite sides of the touch device 10 (as shown in FIGS. 5C and 5F). The main control unit 21 determines which orientation the touch device 10 is held in and which side of the touch device 10 is contacted at the most points of contact to display the shortcut mark A in the corresponding area.

FIG. 8 is a flowchart of an embodiment of a control method illustrating an operation of the touch device 10. The control method is as follows.

In step S101, when the touch device 10 is powered on, the detection device 25 detects a number of points of contact of sides of the touch device 10, detects whether the touch device 10 is held in the landscape orientation or the portrait orientation, and outputs the corresponding first through seventh detecting signals to the main control unit 21 based on the detections.

In step S103, the main control unit 21 generates the holding information, which indicates how the touch device 10 is held, based on the first through seventh detecting signals.

In step S105, the main control unit 21 adjusts the display locations of the at least one shortcut mark A based on the holding information.

The touch device 10 dynamically adjusts the display locations of the at least one shortcut mark A according to the holding information making the touch device 10 of the present disclosure more convenient to use.

In alternative embodiments, the fifth contact detection unit 255 can be omitted, such that only the first through fourth contact detection units 251-254 are used to detect the number of points of contact contacted by the user.

It is believed that the present embodiments and their advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the present disclosure or sacrificing all of its material advantages.
